Kone V3F10

An early V3F system based on an existing general purpose VVVF design. The drives are most often configured for open-loop, geared traction systems in sizes 5.5kW, 11kW, 15kW & 22kW controlled by the TMS50, 375 Microcomputer. By changing the firmware of the standard drive, KONE customised the units to offer a very efficient and safe variable speed drive package. These drives are very reliable and will run for many years once they have been repaired, serviced and tested correctly.
